atoms - How is hydrogen able to emit a light spectrum with only one electron?

When light is shined through hydrogen gas, three colors of light appear. The issue I have with this is that hydrogen has one electron, meaning somehow the electron has to be emitting all three of these colors simultaneously. This, however, would be impossible since a single electron can only make one orbital jump at a time, which in turn means one electron can only emit one color at a time, not three. If anyone can offer an explanation, I welcome it.
